To all whom it may/concern) 7 Be it known that. BERRY G. MoXLnY, a citizen of the United States, residing at Hoquiam, in the county of Grays Harbor,

and State of Washington, has invented certain new and useful Improvements in Porta- 'ble Steam Generators,of which the following is a specification. l

burners and is more particularly adapted to a portable steam generator for supplying steam to the'olliburner used 111 con unct onr witlicrude oil burning engines. With the present system of boilers now 1n use in conjunction with the crude oil burners, it 1s necessary to keep the steam bollers going during the night when the engines are not in use in order to maintaln a'suiiithe fuel used in order tokeep theboilers when a new fire'is needed diflicultyis often experienced in getting the boilers heated in a short time for the reason that there is usually an'insufficient draft. suitable for the burning ofthe wood. With a device of my f character, the loss of time and labor is ob viated andthe boiler with which my invention is connected may be heated in a comparatively short time and at avery low cost. A still further object of my invention is 40 may be easily and quickly placed in posiing of the same will generate its own steam.

A still further object of the invention is to provide a portable steam generator of V ble, and further well adapted for the purposes fo'r which it is designated.

cientamount of steam so thatthe oil' burner" may properly operate the next morning for the purposes wellkn'own. This operation necessitates the employment oi an attendant and also addsjtof the expense of the cost of to provide a portable steam generator which the above mentioned character, which is.

very simple In constructlon, strong and duraj Other objects and advantages of this invention will become apparent during the course of the following description.

In the accompanying 'drawingi orming a part of this specification and in which like numerals ofrefer'ence designate like parts throughout the same,-

generator, and l Figure 4 isa vertical section taken on line 4 4 of Figure 3. Y

In] he drawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates the base orsupport upon which my steam generator is'adapted to be mounted, andthe latter comprises the substantially cylindrical casing'2,'a flange 8 secured to the lower edge or" thecasing and extending therearound is adapted to be held in position on the base by means of the bolts 4, in the manner as clearly illustrated in the drawing. Disposed within the casing -2-adjacent the inner wall thereof is the water receptacle 5, thesame being preferably tubular in cross section and having an angular extension formed at the upper end thereofas further illustrated bythe numeral 6 in the drawing, the purposeof which will hereinafter be more fully described. i

The water receptacle 5 has its lower end threaded onto the supporting base"? and the outer end of the steam dome 6 or trap is also threaded ontovthe cap 8 in the man'- ner as clearly illustrated in Fig. 3 of the drawing. 7 Suitable brackets such as are shown at 9 are provided for the purpose of supporting the tubular water receptacle and; steam dome'6 in proper position within the casing 2. .l/Vith the construction shown in Fig. 3 of the drawing, it will thus be seen.

that a substantially inverted L-shaped'containerj is provided'wherein the longer arm forms the water chamber or receptacle and the shorter arm will form the steam trap.

Adapted to be associated with the water container andsteam dome is the coil pipe I 10, the upper end thereofbeingconnected '85 F gure 3 1s a vertical section of the steam V to the steam dome whilethe opposite or source of supply, whereby water may be supupwardly from the steam dome 6 and .plied to the water receptacle. A valve of any conventional typeand such as is shown at 12, is provided in the supply pipe 11 for the purpose of shutting off the supplyof water to the water receptacle whenever necessary. The casing 2 is also adaptedto.

support the water levelgauge 13, the latter ,being in communication with the water. receptacle 5'1n the usual mannerand for I the purposes well known in the art,

Extending outwardly from the steam dome 6 and through one side'of the casing 2, is the pipe 14 which supports 'thesteam gauge 15. A safety valve 16' also extends through the casing 2 in themanner as shown in Fig.8 of the drawing. 7

For the purpose of generatingusteam' in the steam dome 6, I provide a suitable burner such, as is shown at 17 in the draw- -ing, the latter being adapted to be supported directly below the coil pipe 10. A fuel tank I 18 is also supported on'the base 1 and has a fuel pipe 19 extending therefrom and in communication with the, burner 17 for supplying the proper amountfof fuel to the burner whereby the latter-inayproperly op erate. In the present instanceI desire to use kerosene as the fuel for the purpose of generatmg steam, although 1 0 1s to be understood tliatany other suitable fuel may be used in place thereot. Access tothe burner 17 may which is provided in thecasing 2. I i v The operation of my steam generator may be briefly stated as follows:

With tliewater in the water receptacle 5 up to the level shown in F ig. 3 of the drawing, the heater 17 is ignited and thus will I cause the coil pipe 10 to be heated in such a manner as to generate'a: sufllcientquantity of steam within the. angular, extension formed on the upper end of thewater receptacle, it being understoodthat the water in the pipe 10 will'notbe discharged through the upper end thereof into the steam dome. The steam, thusgenerated in. the steam trap or dome 6 will be then discharged through the suitable outlet pipe 2 1 whichextends 'from the upper portion of: the steam trap or dome, and through the top of the casing 2, into the. outlet pipe 22. The latter is connected at its outer endtothe burner pipe behad .througli suitable door 20,

1,581,760 if" i 23 which may be of any conventional construction, and as is well known in the art, the same is provided witlrthe oil supply pipe 24: and the burner head 25. With a construction of this kind'it will be readily seen that asupply of oil from the pipe 24 and steam from the pipe 22 will be admitted to the burner whereby the same will be sprayed into "the boiler for the purpose of heating the same wherebythe latter will be'caused to operate and further generate steam sufficient to cause the operation of the engme to which the same is connected.

A suitable valve 26 is-provided in the outlet pipe 21 for cutting ofi the supply of steam to the burner as the case nec'essitates It is also to be'understood that when the desired pressure has been reached and sixthcient steam has'been caused to be generated inthe steam dome 6, the heater 17 will be shut ofia In order to render' my device portable; 7

Iprovide a suitable handle 27 on the top of the casing'andasthe entire device isvery lightthe same may be easily transported from place to place without" much difliculty- It will thus be, seen from the foregoing" description, that a steam generator has been provided which is very simple in construction, nexpensive, and further of such construction as to enable the same'to be readily placed in operation andfwillproperly heat" the boiler in a minimum amountof time by supplying the desired generated steam to the same in connection with the o l burner,

so thatloss of'labon andltimeis obviated, and the necessity of having to employ'an'" attendant to watch the'same is also'done away with. s

From the construction or my improved apparatus, it

'will' be seen that I have provided a'simple,

inexpensive and efficient means for carrying out the objects of the invention, and while I have particularly described the elements best adapted to perform the functions set forth, it is obvious that'various changes in form,.'proportion, and in the minor details of construction maybe resorted'to,without departing from the spirit or sacrificing any of the principles of the invention.

Having thus described my invention, what I claim is:

A steam generator comprising a casing,

, a water receptacle having angularly disposed end portions one'end portion being vertically disposed in the casing and the other end portion horizontally disposedin the casing, one vertical wall of the vertically disposed end portion engaging one side of the casing and the end wall of the horizontally "dis-, posed end portion engaging the opposite side of theoasing, the surface of the casing being spaced from the remaining sideportion of the water receptacle to form a comforegoing description of the bustion and heating chamber, a coil located a water inlet pipe connected with the lower in the combustion chamber and connected portion of. the vertically disposed end of the 10 at one end with the lower portion of the ver- Water receptacle and a steam outlet pipe tically disposed end portion of the water reconnected with the upper portion of the ceptacle and connected at its other end with horizontally disposed end portion of the the end portion of the horizontally disposed Water receptacle.
